My favorite guy is the sonar operator. I think he's got an iPad down there and is entertaining himself by playing Angry Birds, because he SURE doesn't pay any attention to the sonar!
Tell him to follow a target and he does for a few minutes. Tell him to follow a merchant and he doesn't pick up the escort about to blow you to atoms. He is just utterly brain dead, or intent on that iPad.
I just want to know how he gets a wireless Internet signal when we're 200' deep!
